Title: Intumescent fire barrier material laminated with  restraining layer
Inventor: LICHT RICHARD R
IPC: H02G3/22
Filed: 1981-05-13
Granted: 1984-06-12
Abstract: ABSTRACT           An intumescent composite comprising a layer of intumescent sheet material having a restraining layer laminated thereto provides a superior intumescent barrier for use in sealing penetrations through floors, partitions and ceilings from smoke, fire, gas and water passage.  The restraining layer causes the char forming during an intumescent reaction to be generated in a directionalized manner so that cavities into which the intumescent composites are placed are optimally filled. The intumescent composite can have holes punched in it and can be used in fire protection applications where air circulation is desired.  In the event of a fire, the expansion of the intumescent composite is in a direction which enable the punched holes to be quickly filled.

Abstract: ABSTRACT    Apparatus for measuring progressively the absorbance changes of a large number of aliquots from a plurality of different samples. The sample introduction, testing instructions, aliquot preparation, reagent dispensing, absorbance measuring and data recording all can be accomplished in a continuous mode of processing.  Stat and batch operation also can be accomplished.  The aliquots are in an array of cuvettes which is advanced slowly along a circular path.          Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly along a similar circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that cuvette completes one circuit of its path.  The photometric detectors can operate at several different wavelengths.  Many different chemical reactions can be monitored at the same time,  The radiant energy passing through each cuvette is received by the continuously moving photometer means, is converted electrically into a digitized value proportional to absorbance and is transmitted digitally from the moving assemblage of photometric detectors, cuvettes and electrical components to a stationary receiver.  In one embodiment, the digital transmission is in the form of a pulsed train of light signals.  In another embodiment, one or more slip rings transmit electric signals from the moving assemblage to the stationary portion.  Suitable drive elements, sample and reagent storage and transfer mechanisms as well as cuvette laundry means may be provided as part of the complete apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE        A windshield repair device comprising a vacuum cup with a built-in piston and cylinder assembly is characterized by a transverse opening in the cylinder so that when the piston is partly withdrawn, gas bubbles can be drawn out of the repair liquid by the vacuum holding the cup in place against the glass.  In operation, after the bubbles are removed from the liquid, the piston is moved toward the glass.  The piston closes off fluid communication through the transverse opening in the cylinder, and as it moves further toward the glass, it forces repair liquid into the damaged area.  The invention permits the cylinder itself to be used as a reservoir for repair liquid, while allowing gas bubbles to be removed from the liquid by the vacuum holding the cup in place.

Abstract: TITLE: TOYS UTILIZING FLUID PROPULSION DEVICE     ABSTRACT      A series of toys having unique motions are activated by a fluid propelled propulsion device. The propulsion device includes a housing with a cylinder located thereon. A pressurized fluid reservoir connects to the cylinder via a valve. The valve has provisions for introducing pressurized fluid into the cylinder and exhausting pres-surized fluid out of the cylinder. A piston is located in the cylinder and in response to introduction of pressurized fluid into the cylinder, moves in a power stroke. This is followed by an exhaust stroke wherein the piston moves in the opposite direction. A piston output member is associated with the piston and extends out of the cylinder. The piston output member moves linearly in response to movement of the piston in its power and exhaust strokes. A connecting mechanism connects the piston output member and the valve. The connecting mechanism-includes a first movable member and a second movable member and a biasing member. The first movable member is operatively associated with the valve and controls the position of the valve for charging and exhausting the cylinder. The biasing member interacts with the first member for controlling the valve. The second movable member moves the first movable member to initiate at least one of the charging or exhaust operations of the valve in response to movement of the piston. The second movable member can move the first movable member to initiate the other of the charging or exhaust functions of the valve in response to movement of the piston in the opposite direction, or an independent movement can be utilized to initiate this operation.

Friction drive discs are located to the oppo-site sides of the spool gear and coupling discs abut the drive discs.  The coupling discs are connected to the spool shaft.  "Belleville" disc springs are mounted in abutting engagement with the outer coupling discs and the nut is threa-ded on the shaft to collapse the springs onto the coupling discs to increase the spring force and lock the gear to the shaft.  The nut may be released to reduce the spring force and effectively decouple the shaft and gear, thereby permitt-ing controlled release of the tension in the spring drive means.

Abstract: ABSTRACT:       A device for controlling the speed of a d.c. motor (M), which device employs a method in accordance with which the motor supply voltage (V) is controlled by a control voltage (Vo) supplied by a comparator circuit which compares a reference signal (Sref) with a signal (SV) representing the speed of the motor (M), which signal (SV) is derived from a signal (SM) induced by the motor rotation via a signal processing circuit.  According to the invention the motor supply voltage (V) is controlled by the control voltage (Vo) by means of a circuit having a "negative resistance" (-R), which circuit at least partly compensates for the internal resistance (r) of the motor.  The device is employed in magnetic-tape sound recording and reproducing equipment, especially in equip-ment to be installed in motor-cars.

Abstract: ABSTRACT OF THE DISCLOSURE   Focus sensing using a light detector array is accomplished in an optical recording system using the light beam returned from the recording media through the objective focusing lens by passing the beam through a spherical focussing lens using a mask such as a knife edge which only passes a portion of the beam to the light detector array.  The light detector array is matched to the mask and detects the different partial image patterns formed as a result of the close to focus condition with the recording media too far away from the objective lens and the near to focus condition with the media too close to the objective lens.  In the focused condition, the light detector array receives a comparatively fine focused spot of light.  Alternative embodiments of the present invention may use a cylindrical lens which in the focused condition creates a longitudinal bar of light.  Further alternative embodiments may be made with a spherical Fresnel lens or a cylindrical Fresnel lens which create larger areas of light, round and bar shaped, respectively, in the focused condition.
